drm/ttm: allow reserving more than one shared slot v3

Let's support simultaneous submissions to multiple engines. v2: rename the field to num_shared and fix up all users v3: rebased Signed-off-by: Christian König Reviewed-by: Michel Dänzer Reviewed-by: Junwei Zhang Reviewed-by: Huang Rui Signed-off-by: Alex Deucher

drm: Remove drm_global.{c,h} v2

2018-11-05T19:21:21Z

The content of drm_global.{c,h} is obsolete. v2: rebase on dropping TTM functionality Signed-off-by: Thomas Zimmermann Signed-off-by: Christian König Reviewed-by: Junwei Zhang Signed-off-by: Alex Deucher

drm/ttm: initialize globals during device init (v2)

2018-11-05T19:21:21Z

Make sure that the global BO state is always correctly initialized. This allows removing all the device code to initialize it. v2: fix up vbox (Alex) Signed-off-by: Christian König Reviewed-by: Junwei Zhang Signed-off-by: Alex Deucher

drm/ttm: use a static ttm_bo_global instance

2018-11-05T19:21:20Z

As the name says we only need one global instance of ttm_bo_global. Just use a single exported instance which is save to initialize multiple times. Signed-off-by: Christian König Reviewed-by: Junwei Zhang Signed-off-by: Alex Deucher

drm/ttm: make the device list mutex static

2018-11-05T19:21:19Z

This way it can protect the whole BO global state. Signed-off-by: Christian König Reviewed-by: Junwei Zhang Signed-off-by: Alex Deucher

drm/ttm: use a static ttm_mem_global instance

2018-11-05T19:21:18Z

As the name says we only need one global instance of ttm_mem_global. Drop all the driver initialization and just use a single exported instance which is initialized during BO global initialization. Signed-off-by: Christian König Reviewed-by: Junwei Zhang Signed-off-by: Alex Deucher

drm/ttm: Provide ttm_bo_global_{init/release}() for struct ttm_bo_global

2018-11-05T19:20:52Z

So far, struct ttm_bo_global_ref was the only way of initializing a struct ttm_bo_global. Providing separate initializer and release functions for struct ttm_bo_global gives drivers the option of implementing their own init and release callbacks for drm_global_references of type DRM_GLOBAL_TTM_BO. The original functions for initializing and releasing via struct ttm_bo_global_ref are wrappers around the new interfaces.

drm/ttm: Rename ttm_bo_global_{init,release}() to ttm_bo_global_ref_{,}()

2018-11-05T19:20:52Z

The functions ttm_bo_global_init() and ttm_bo_global_release() do not receive an argument of type struct ttm_bo_global. Both take a struct drm_global_reference that contains points to a struct ttm_bo_global_ref. Renaming them reflects this.

drm/ttm: Export ttm_bo_get_unless_zero()

2018-09-28T06:55:10Z

Export ttm_bo_get_unless_zero() to be used when looking up buffer objects that are removed from the lookup structure in the destructor. Signed-off-by: Thomas Hellstrom Reviewed-by: Sinclair Yeh Reviewed-by: Christian König

drm/ttm, drm/vmwgfx: Move the lock- and object functionality to the vmwgfx driver

2018-09-27T13:19:20Z

No other driver is using this functionality so move it out of TTM and into the vmwgfx driver. Update includes and remove exports. Also annotate to remove false static analyzer lock balance warnings. Signed-off-by: Thomas Hellstrom Reviewed-by: Christian König
